MULTIPLE-BARREL MACHINE-GUN.

Specification of Letters Patent.

Patented Oct. 28, 1919.

11, 1916. Serial N0. 125,026.

To all whom it may concern Be it known that I, JACQUES LUGIANI, a citizen of the French Republic, residing at 100 Rue dAmsterdam, Paris, France, have invented certain new and useful Improvements Relating to Multiple-Barrel Machine- Guns, of which the following is a specification.

This invention relates to multiple barrel machine guns in which the barrels are each set and fixed in determined positions for securing any desired dispersion of the group of projectiles discharged. According to the invention the barrels are of different lengths.

The accompanying drawings show one construction in which the invention is carried into effect with reference to a gun forming the subject matter of the co-pendmg application No. 49368 of 7th September, 1915, of which this application is a divlsion.

Figure 1 is a side elevation showing a gun to which the invention is applicable.

Fig. 2 is a plan corresponding to Fig. 1.

Fig". 3 is a plan view showlng the assemblage of barrels with the barrel diverglng apparatus in place for ad usting the said barrels.

Fig. 4: is a section to a larger scale at right angles to the barrels, on the l1ne EE m Fig. 3;

Fig. 5 is a plan view of the extremity of the barrels with the barrel diverging apparatus in place, the cover of this apparatus being removed;

Fig. 6 is a vertical longltudinal section of the extremity of the barrels with the barrel diverging apparatus in place.

In the embodiment of the inventlon here illustrated, the barrels 1 of the gun are, as shown more particularly to Figs. 1 and 2, arranged in three horizontal rows each comprising eleven barrels in this case therefore, the gun comprises thlrty-three barrels; 1t will of course be understood that this number can be varied and that the gun may comprise any number of barrels. Similarly, the barrels may be differently arranged; for example, instead of being superposed, they may be arranged quincunx fashion, or staggered. The number of barrels is determined more particularly by the purpose for which the gun is intended and the caliber adopted.

As shown in Figs. 1 and 2, the barrels are of different lengths, the longest in each row being preferably arranged in the middle. This difierence of length plays an important part in the precision of firing and in preventing the projeotiles from encountering each other in space.

In the construction illustrated, the barrels 1 are screwed at their base into a block 2 in which are bored, in line with the barrels, the chambers for the reception of the cartridges. The block 2 slides in a cradle under the influence of the recoil.

T he barrels are mounted toward their outer ends so as to furnish a divergent fire.

- The means employed for this purpose at 9 (Fig. 1) is constituted by a steel frame 10 (Fig. 4:) this frame, which is rectangular in form, serves as support for a series of vertical screws 11 and for a series of horizontal screws 12 which, as hereinafter explained, permit of insuring the individual adjustment of each barrel.

Referring to Fig. 4, each barrel a of the upper row, it will be noted is furnished with a block or enlargement 13 extending as shown in Figs. 5 and 6. The rod of one of the screws 12 passes through the upper part of each of the blocks that it is necessary to traverse; the housing for this rod in these blocks has a diameter slightly greater than that of the rod to permit of the independent lateral adjustment of the barrels; nevertheless the collars 14 provided at the end of the rod of the screw, outside its housing in the block where adjustment is to be effected, clamp that block firmly in such a manner that from any movement of the screw in the wall of the frame 10 a movement of equal value of the corresponding barrel in a horizontal plane results. Each of the blocks 13 is provided also with means for engagement with a screw 11 in such manner that the screw serves to adjust the position of the respective barrel in a vertical plane, lateral movement of the barrel being permitted under the adjustment of the corresponding screw 12. For the purpose two collars l5 15 (Figs. 4 and 6) mounted upon the end of the screw 11 bear against the wall of a recess in the block in such a manner that a displacement of the corresponding barrel a in a vertical plane corresponds to the displacement of the respective screw 11 on its rotation in its position on the frame 10.

It will thus be noted that with the two screws 11 and 12 it is possible to displace each of the barrels a either in the vertical plane or in the horizontal plane, within the necessary limits. Consequently it is possible to adjust the position of all the barrels in each roW (eleven in the example illustrated) in such a manner as to obtain any desired dispersion of the group of projectiles discharged by the gun.

Although Fig. 1 shows the barrel diverging apparatus in position on the barrels, it Will be understood that this apparatus does not remain permanently upon the gun but can be removed as soon as the adjustment is efiected and the barrels have been fixed by any suitable means.

I claim 1. In a multiple barrel machine gun having a group of barrels, means for setting the said barrels in divergent positions, consisting of a transversely disposed inclosing frame surrounding the group of barrels near their outer end, a series of vertical adjusting screws and a series of horizontal adjust ing screws carried by the said frame, the said screws of each set being connected at their inner ends to the respective barrels, substantially as described.

2. In a multiple barrel machine gun having a group of barrels, means for setting the said barrels in divergent positions, consisting of a series of vertical adjusting screws and a series of horizontal adjusting screws carried by a frame, the said screws being rotatable but positively connected at their inner ends to the said barrels for the vertical and horizontal adjustment thereof, substantially as described.
